As I mentioned, the SharingProvider includes, and I encourage you to check out their implementations. To begin the sharing process, add the following code to your persistentContainer below the // TODO: 1 comment: This code configures the shared database to store records shared with you. and operate on the objects I share with them. Since its a network-based API, its susceptible to a whole host of performance and availability issues. persistentContainer calls this method. The code above stores a reference to each store when its loaded. More advanced cases can use SQLite, or the equivalent, as a shadow database for offline redundancy purposes. Basic CloudKit Setup CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. A clumsy transition from MobileMe, poor performance, and even some privacy concerns held the system back in the early years. Finally, I invoke UICloudSharingController's completion block with the results provided by NSPersistentCloudKitContainer, which tells it I'm ready to continue the sharing flow. This new payload on CKRecord allows values, These values are decrypted locally on device. create shares for objects, and accept sharing invitations. Page - Sharing data between User Controls without access to the Page class - Accessing data between user controls WPF - Passing data between user controls in wpf - Pass data between parent child user controls . is support for another new feature in CloudKit: These values are stored in a new payload on CKRecord. In this session, I'll show you how to easily build applications that use NSPersistentCloudKitContainer to share data with multiple iCloud users. Also, to change the sharing permissions because it doesnt work properly on a simulator. This takes you to a screen to add a recent destination you visited. introduced in the "What's New in CloudKit" session. We call them the owner and the participants. Select Private Database. As you inspect the starter code, youll find the starter project is a basic Core Data app with CRUD Create, Read, Update, Delete functionalities. The following code, for example, creates a CKShare object containing the record to be shared and configured for read-only access: Once the share has been created, it is saved to the private database using a CKModifyRecordsOperation object. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Here I'm setting the isSharedBlock to call the contains method of the set I created. It accepts the share and adds the necessary metadata into the sharedPersistentStore. These are all the changes I had to make for my first demo, but my application also needs to effectively communicate what objects are shared, who they're shared with, and what those participants can do. that controls who can access these zones that I own. that is allowed to operate on those objects in some way. Is something like this (or even better) available with the new CloudKit? Checks whether the object is shared. Heres Apples sample project on Synchronizing a Local Store to the Cloud. bookmark, personalise your learner profile and more! and some of the permissions on the shared album. It has a wide variety of actions I can take. This doesn't seem to work. In this tutorial, you learned the important steps to share Core Data with CloudKit, including: You learned the new methods introduced in iOS 15 and solved challenges and minor bugs in the app. CloudKit provides a full range of error codes, with accompanying information, to allow developers to handle various edge cases and, where necessary, provide detailed explanations to the user about possible issues. So, an offline mode must be carefully considered. Does Cast a Spell make you a spellcaster? The UICloudSharingController class provides a pre-built view controller which handles much of the work involved in gathering the necessary information to send a share link to another user. So I'll change the share options to mark the share as View Only. Generally speaking, youll be working with an NSManagedObject from your view. for you to build tests in your own applications. And I'd like to show you one specific call site. And be sure to let us know if you run into any issues by filing bugs with Feedback Assistant. To achieve this, iOS 15 introduces share(_:to:). So how does NSPersistentCloudKitContainer know where to keep your records? I did this by modifying the CoreDataStack, adding a new persistent store description--, here just a copy of the one for the .private store, Then, I set its CloudKit container options, to be configured to mirror persistent stores, I adopted a new method on NSPersistentCloudKitContainer, share(_ managedObjects: to share: completion:). The way to enable these silent notifications is to set the shouldSendContentAvailable property on the CKNotificationInfo instance, while leaving all of the traditional notification settings (shouldBadge, soundName, and so on) unset. On Jermaine's device now, I'll accept the new share. It has a wide variety of actions I can take, including a number of ways to share. we think of our objects in terms of NSManagedObject. To change the permissions and access to this data, Apple has done all the heavy lifting for you. Asking for help, clarification, or responding to other answers. You would need a unique identifier for that CKRecord. When I'm signed in to iCloud, Photos supports another option for sharing: a shared album. As always, I can't wait to see what you build with NSPersistentCloudKitContainer. A general guideline is to use com.company_name.bundle_identifier. No specific cutoff point is specified (a maximum of 1MB total is recommended for each CKRecord), but as a rule of thumb, just about anything that feels like an independent item (an image, a sound, a blob of text) rather than as a database field should probably be stored as a CKAsset. Thanks for contributing an answer to Stack Overflow! By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. to show that the post is part of a share. To improve this, go back to HomeView.swift. So let's look at how I've changed my application to communicate these states and privileges. If it is, then this object is already shared. Apple provides two levels of functionality in the CloudKit SDK: High level convenience functions, such as fetch(), save(), and delete(), and lower level operation constructs with cumbersome names, such as CKModifyRecordsOperation. NSPersistentCloudKitContainer manages these zones and automatically assigns records to them. I'm Nick Gillett, an engineer here at Apple on the Core Data team. There's a lot of new API to learn about. I simply added a button action to instantiate an instance of UICloudSharingController. to test these decision points by injection. I've already saved Heather and Mary in my address book. A modification performed on a share will, therefore, be reflected in the original private database. It is capable of handling large file transfers seamlessly. this new Allows Cloud Encryption checkbox. Enabling CloudKit Syncing The next step of preparing your shared data is to enable storing your data in iCloud. Before an app can take advantage of CloudKit sharing, the CKSharingSupported key needs to be added to the project Info.plist file with a Boolean value of true. The solution is in CloudSharingController.swift. Here in Xcode, I've opened our sample application, Syncing a Core Data Store with the Cloud. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. by the presence of their objectID in this set. my application can access data in both stores. I'll give it a simple title-- "Sharing demos are great"-- and tap Done. Have a question? Saving records is, perhaps, the most complicated operation. After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. Since CloudKit is deeply tied to Apples operating systems and devices, its not suitable for applications that require a broader range of device support, such as Android or Windows clients. In theory, you needed only three steps. But ideally, we would have a single place directly in the Photos app where my friends and I can share our photos with each other. Open CoreDataStack.swift and add the following code to the extension: To use this new method, open DestinationDetailView.swift. It comes with a Dictionary of contained CKErrors that deserve more careful inspection to figure out what exactly happened during a compound operation. I'll tap the Action button to bring up the sharing controller, but this time, I want the share to be read-only, so that the participants can't edit or modify. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. directly to specific call sites in my application. One user shows up as a Owner and the other as a Private User, with both users having Read-Write permissions. Then, select the CloudKit checkbox to enable the feature. shared CKRecords are contained inside a shared CKRecordZone. In the iCloud section, tap the + button underneath Containers to add a custom container. Thats it! Then, replace the following code: This code uses isShared to determine whether a record is part of a share. share NSPersistentCloudKitContainer between app and extension, Core Data sharing with CloudKit: Unable to Accept Share. However, you dont have any metadata about the share. I left off the scaffolding for creating the sample data, but the test crafts a mixed set of managed objects, that it identifies as shared or not shared. In my .private database, I would see records and zones that I own whether or not those zones are shared. Youll use the default share when you present the CloudSharingView. New in iOS 15 is acceptShareInvitations(from:into:completion:). Under the Schema section, select Indexes. Jordan's line about intimate parties in The Great Gatsby? Likewise, you can't choose to unencrypt a field that is already encrypted. If you sent the invitation from a real device, that can be a simulator. Continue with Recommended Cookies. The end goal is not only to display shared entries but also to get information about the people participating in the share. If I tap on it, I can also see the participants displayed at the bottom of the detail view controller with their role, permissions, and acceptance state. You need to extract information about the participants of this share. Please check your Internet connection and try again. Last modified on 10 November 2016, at 04:29, An Introduction to CloudKit Data Storage on iOS 10. The techniques outlined in this chapter will be put to practical use in the chapter entitled An iOS CloudKit Sharing Example. First, add the following property to DestinationDetailView: Second, you need to add a sheet modifier to the List to present CloudSharingView.

For example, the zone that NSPersistentCloudKitContainer manages. The most common options are via email or text message. More importantly, you have a foundation for adding more advanced CloudKit functionality. for the view controller, completing the injection. provided by NSPersistentCloudKitContainer. In this post, we will talk about zone sharing. Amazing! But this isn't how NSPersistentCloudKitContainer works. Each of these is mirrored to a persistent store in my application, one using the .private database scope and the other using the .shared database scope. 2 Answers Sorted by: 8 In iOS 10 / macOS 10.12, it is now possible to share hierarchies of records in a user's private database with other users. The most amazing part is that because your data is now synced in iCloud, you can run your app on a completely different device thats signed in to the same iCloud account and see all your data! . This is the default database that data gets written to. informative user interfaces for our users. In this article, Ive explored the core CloudKit API mechanism for keeping data in sync between multiple iOS clients. Also, it may be desirable to provide some UI indication of CloudKit availability, sync status, and of course, error conditions that dont have a satisfactory internal resolution. here, the shared store for my application. Lets look now at a layer built on top of that to manage these operations in the context of a specific Note. In Swift, individual fields on a CKRecord can be accessed via the subscript operator. That method works for documents saved to the current iCloud account. CloudKit supports both structured and bulk data. A participant is any other iCloud account that is allowed to operate on those objects in some way. Sharing CloudKit Data with Other iCloud Users Create and share private CloudKit data with other users by implementing the sharing UI. This is a cute trick in Swift that allows me to simply check if the provided objectID is in sharedObjectIDs. Naturally, this domain knowledge is reflected in the APIs we have built for NSPersistentCloudKitContainer. Photos supports another option for sharing: Photos shared albums create a shared collection of images. If necessary, you then pass the updated server record to CloudKit to write the new record. Loading a note is very straightforward. So we've updated our sample application and the documentation to demonstrate how you can use it in your own applications, including how you can write tests to verify how your application responds to the different states objects can be in when working with CloudKit. When storing data via CloudKit, CloudKit Console allows you to interact with the data in question and perform several other functions such as viewing logs. If its not shared, create the share from the destination object. But first, a quick discussion of CloudKit Errors. This is new iOS 15 and allows NSPersistentCloudKitContainer to be configured to mirror persistent stores to the .shared CloudKit database. And exactly how much did I have to change in the sample application? This is your Destination entity in Core Data. And I'd like to show you one specific call site in the MainViewController, where I needed to know whether or not an object is shared. Im going to take a fairly deep technical dive into the CloudKit API to explore ways you can leverage this technology to make awesome multi-device apps. Since CloudKits notifications are built on top of the iOS notification system, you have to be on the lookout for these conditions. Not the answer you're looking for? by tapping the Edit button, I can't delete this post. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. For example, if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign the provided post object to that share. If you have any questions or comments, please join the forum discussion below. When a notification comes in that a record has changed, CloudKitNoteDatabase will do the heavy lifting of fetching the changes from CloudKit. Launch a simulator.

What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? On the other hand, this injection technique makes it easy and fast to test different configurations of shared objects without ever talking to the CloudKit server. Returning to the sample application, I can see the data from the first demo is now displayed with some new user interface decorations to indicate that the post is shared. These can be normal push notifications familiar to iOS users (such as sound, banner, or badge), or in CloudKit, they can be a special class of notification called silent pushes. Each participant will also have their own collection of devices. Although this adds complexity to the client, its ultimately a far better solution than having Apple come up with one of a few server-side mechanisms for conflict resolution. It's called the SharingProvider. Build and run. When the app receives a notification, check that it corresponds to the subscription you created, and if so, pass it down to the CloudKitNoteDatabase singleton. Within a CKDatabase are CKRecordZones, and within zones CKRecords. The first step does a one-time setup in preparation for writing the record, and the second step passes the assembled record down to the singleton CloudKitNoteDatabase class. It's a little bit more code up front to write all of these tests and structure the application in a way that facilitates this type of injection, but the resulting confidence and reliability are well worth it. To get the most out of this session, check out our previous videos on NSPersistentCloudKitContainer: "Using Core Data With CloudKit" from WWDC19 and "Sync a Core Data store with the CloudKit public database" from WWDC20. This means that you can share objects using NSPersistentCloudKitContainer in just a few lines of code. Once the CloudKit schema is pushed to production, we can't change any of the field types. Hi. However, network conditions and performance constraints can cause individual notifications to be dropped, or multiple notifications to intentionally coalesce into a single client notification. Was Galileo expecting to see so many stars? Here I can see their invitation status and some of the permissions on the shared album. Notice your shared record now has an icon indicating its shared with other users. I want to send each person an invite to work on this post with me via email.

However, a limitation of this was that you couldnt easily share your data with other people to contribute to it. Users may not be signed in, they may have disabled CloudKit for the app, they may be in airplane modethe list of exceptions goes on. It is important to be aware that when a share recipient accepts a share they are actually receiving a reference to the original record in the owners private database. The SharingProvider protocol makes it easy to test these decision points by injection. wherever you need to customize your user interfaces. about the CKShare a specific post resides in. Also, the service itself must protect against a range of potential issues, such as unauthorized requests, conflicting changes, and the like. Then, it sets the persistent store based on the scope. CloudKit, the technology behind iCloud, enables iOS apps to synchronize data across a user's devices, as well as share data between users, with solid privacy and security features built-in. It brings together a huge amount of domain knowledge. You could use the recordId for this. Next, I'll tap Mail and invite Jermaine and Mary.

You can download the completed project files by clicking the Download Materials button at the top or bottom of the tutorial. Owners create and share objects with a set of participants. Due to network latency, airplane mode, and such, CloudKit will internally handle retries and such for operations at a qualityOfService of utility or lower. Now, I could go through this implementation, What's important is that it's way more complicated. Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. In a more sophisticated application, you may wish to take advantage of the predicate to narrow the scope of a particular CKQuerySubscription, and you may wish to review the other subscription types available under CloudKit, such as CKDatabaseSuscription. I'll open the CoreDataCloudKitDemo managed object model, and there's a specific property on the post entity I want to show you called location. Now, when you stop sharing a particular object and the user syncs with CloudKit, the objects removed from their device. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. Apps can support such use cases by moving user data to CloudKit and implementing a data sharing flow that includes features like share management and access control. Here I used isShared to decide whether or not to convert the title of a post to an attributed string and prefix it with the person.circle symbol to show that the post is part of a share. Before CloudKit, inconsistent behavior and weak debugging tools made it almost impossible to deliver a top quality product using the first generation iCloud APIs. Heather, Jermaine, Percy, and Mary are all test accounts I regularly work with when I'm building sharing features. CloudSharingView conforms to the protocol UIViewControllerRepresentable and wraps the UIKit UICloudSharingController so you can use it in SwiftUI. When you app is opened with such a link, then you can download the CKRecord and you will have the file in a CKAsset. depending on whether or not they are the owner of those zones. Let's look at that change in a bit more detail. Once you add the destination, tap the destination to view DestinationDetailView.
